Margherita Missoni
Libation location: Beatrice Inn, Le Baron, Cannes Film Festival
Wearing: To-the-floor Missoni and a headband
Plus-one: Tatiana Santo Domingo
A new crop of Euro heiresses seems to shoot up every few months, sporting painfully hip clothes and impressive hair, but Margherita Missoni—heir to the Italian knit empire founded by her grandparents Tai and Rosita—has been mugging for Patrick McMullan for years (and she's still only 27). The girl is everywhere: front-row perches in New York, red carpets in Cannes, late-night Parisian bashes for friends like Riccardo Tisci and Giambattista Valli…she's a full-time brand ambassador. In addition to slyly advertising the family business via her au naturel look and Missoni maxi dresses, Margherita signed on in an official design capacity last season as the head of the family's accessory line. All work, all play.
